The R-Type BOV is good for those who have replaced their stock turbos with larger ones and are running more boost pressure. GReddy offers the R-Type BOV, which should only be used for high-output race engines in excess of 500hp. A blow off valve relieves pressure that builds up in the intake system when the throttle is closed quickly (between shifts, for example). This valve is an extremely import...
The HKS Super Sequential Blow-Off Valve (SSQV) is a pull type relief valve. The SSQV is actuated by pressure alterations only, ensuring quick valve response and complete closure during idle. Typical blow-off valves utilize large valves in order to accommodate high boost/high hp applications. However, these large valves react slowly and require high activation pressure to open. Smaller, fast reacti...
71004-AM015 MITSUBISHI Lancer Evolution GSR & MR 2008 Includes 3 Inlet and 1 Outlet Polished Aluminum Pipes
HKS Super SQV (Super Sequential Blow Off Valve) uses a unique sequential valve structure and a differential pressure control system, which allows for a broad operation range from low boost to high boost. All vehicle specific Super SQV kits include both the HKS Triple Fin Sound ins...
HKS Racing Bypass Valves function similar to Standard Bypass Valves but incorporate an additional pressurized port to aid under severe boost conditions. They can also be used as safety "pop-off" valves if the second port is connected to a pressure source. ...
The HKS Super Sequential Blowoff Valve (SSQV) is a dual stage pull type relief valve.
Unlike other blow off valves that are push type, the HKS Sequential will not leak under high boost conditions nor under vacuum at idle.
The HKS Sequential Blowoff valve being of a pull type valve structure, the SSQV can not physically leak under any level of boost because boost pressure also keeps ...
Designed for high performance, the TurboXS Blow Off Valve - Type H relieves compressor pressure surge caused by changing gears or backing off the throttle quickly. This valve is an extremely important part of any turbo system allowing quick boost response and greatly increasing the life of a turbocharger. The BOV Type H provides greater venting flow than the Type S and is designed for turbo charge...
The TurboXS Blow Off Valve - Type S is designed to release compressor pressure surge caused by changing gears or backing off the throttle quickly. This valve is an extremely important part of any turbo system allowing quick boost response and greatly increasing the life of a turbocharger. The BOV Type S is designed for small to medium sized turbo charged engines running from 5-15 psi boost, howeve...
